Velos Lightning and GEMS Automatic Numbering Machines

(Sorry for the poor autofocus) Here are two automatic numbering machines, i.e. self-inking hand stamps that print increasing numbers. One is a Velos Lightning, made in England in the 1930s, and the other is by GEMS and is made in the Netherlands. Both have a selector switch to allow numbers to be printed 1, 2, 3 or 4 times before increasing.
